Simplifying 4x2 + -8x + 49 = 0 Reorder the terms: 49 + -8x + 4x2 = 0 Solving 49 + -8x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 12.25 + -2x + x2 = 0 Move the constant term to the right: Add '-12.25' to each side of the equation. 12.25 + -2x + -12.25 + x2 = 0 + -12.25 Reorder the terms: 12.25 + -12.25 + -2x + x2 = 0 + -12.25 Combine like terms: 12.25 + -12.25 = 0.00 0.00 + -2x + x2 = 0 + -12.25 -2x + x2 = 0 + -12.25 Combine like terms: 0 + -12.25 = -12.25 -2x + x2 = -12.25 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -12.25 + 1 Reorder the terms: 1 + -2x + x2 = -12.25 + 1 Combine like terms: -12.25 + 1 = -11.25 1 + -2x + x2 = -11.25 Factor a perfect square on the left side: (x + -1)(x + -1) = -11.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
